libopencoreplayer.so中包含了以下内容：

* 一些解码工具

* 文件的解析器(mp4)

* 解码工具对应的Node

* player的引擎部分(engines/player/Android.mk)

* 为Android的player适配器(android/Android.mk)

* 识别工具(pvmi/recognizer)

* 编解码工具中的OpenMax部分(codecs_v2/omx)

* 对应几个插件Node的注册

libopencoreplayer.so中的内容较多，其中主要为各个文件解析器和解码器，PVPlayer的核心功能在engines/player /Android.mk当中，而android/Android.mk的内容比较特殊，它是在PVPlayer之上构建的一个为Android使用的播放器。
